SCALE.

To all whom t may concern:

Be it known that i, MORRIS M. SCHWARTZ, a citizen of .the United States, and a resident of the town of North Bergen, in the county oi" Hudson and State of New Jersey, have invented a new and Improved Scale, ci' which Sur aces of the' members oi the scale from' friction with a drawing" and the Wear lconse- Iquent thereto, and 'toi avoid the necessity of raising the edges oi the scale lfrom a drawing, thereby oliviating the unsteadniess dueto lack of contact and the. errors frequently arising therefrom.

A flurtlier object of in providing a scale 4with either a box Wood or a whitesurface, or with al box'wood surface Y on one or more faces, and a White surface on the remaining faces.l V v Such objects I accomplish by the 'means illustrated in the accoml'ianyingdrawings,-

which embody l my invention in Vits preferred form,- in which Figure l isa perspectiveview ofa lscale' embodying my invention; Fig. 2 is a perspective view of-Athe device shown' in Fig. 1`

with one of the scale members removed; Fig.` 3 1s 'a perspective view of a scale embodying my invention 'removed from the holder; and

Fig. 4 is a side elevation of a section of a scale j provided vvitlra boxwoodfaee and a white face.

As illustrated inv the drawing, tlie scale` comprises a central'li'old'cr having a plurality oi' double members detachably scc uredtliereto. The holder'con'iprises""segmental see.

my invention consists' Patented June 18, 1907,

from each other and form receptacles adapted to receive the inner portion of the several scale members. These members are pro'- vided on opposite vsides with centrally dis'- posed grooves 7 extending longitudinally of the scale members and adapted toiengag'e the free edges 2 ofthe. segmental guard sections of the holder. inclined faces 8 eX- tend from the central longitudinal grooves 7v Ito the ou ter edges of the 'members Where they r meet at an acuteA angle forming bearing 'dges 9. When the device is in use, these hearing edges form a bridge and support the scale, as illustrated in Fig. 1, thereby raising 'and protecting the divided surfaces from Wear. ber is provided. with a division differing from all of the divisioiisof the other surfaces of the same iiilernber of the scale, and also differing from all the' divisions of-all of the remaining members of the scale.

other purposes at will.

The desirability of scale provided with either box Woord. or' a White surface is commonly recognized by the u sersf'of scales of the character shown herein, and my invention contemplates the use of abort-,wood face 10, or awhite face ll'as- Each' of |the surfaces of a scale mem- By means oi such construction a scale is formed 'provided with members having divisions adapted to be v used foreither architectural, engineering or..

lia-ving bthe face of a y may be desired; thus on both sides of a memd .ber the seale'i'nayl'be provided with similar Y surfaces, or one of the faces on one side of a memberniay be' provided with a4 Wlutesur- `face and the other face With a'box WoodsurjI t face', and the op osite side of theVA member may be provide ,with similar surfaces `re versed. The .holder'upon which the` mem'- hers of the scale are mounted, .is adapted to be conveniently handled'and used tounuch better v'advantage than the scales'novv in use having triangular wings provided with divisions which are se arated from .eachother only by narrow sha low grooves.

While for convenience andstrength of construction prefer to support the sec tions of the holder in the manner shown and having similar be used 'for this purpose described herein, other means capabilities may Without departing from my invention.

A scale comprising a holder and plurality of l grooves engaging said holder, and beveled' races` extending trom said grooves Vto the 2 5 outer edges of the members, and so inclined what ,l claim as new and desire to secure by Let having centrally disposed longitudinal grooves on opposite sides thereof, and beveled faces extending from said grooves and meeting at the edges of the scale 2. A rhornb scale having centrally disposed longitudinal grooves on op osite sides thereA of, and beveled faces of diiierent character of iinish extending from said grooves and converging at the edgesloi the scales in acute members having longitudinal relatively to the holder that only the edges of two adjacent members bear on a supporting surface. l

retaining means adapted to engage the central portion of said scales intermediate of said bevels.
